LIN'oTYPEl-M'ACHINE.

sPoIEIcArIoN forming part @t Letters Patent No. 651,496, dated aune 1 e, 1960. Applicatiu filed March Z7, 1900. Serial No. 10,397. (No model.)

.To all w/w'nt t may concern.-

Be it known that I, SAMUEL SMTH, of New York, (Brooklym) countyof Kings, and State of New York, have invented a new and useful Improvement in Linotype-h/Iaohines, of

which the following is a specification.

In the commercial Mergenthaler linolypemachine of the present day, such as repre-l sented in Letters Patent No. 557,000, the

ro type-matrices are carried in an inclined magazine, from which they are discharged by the action of oscillating escapements located'in the under side of the magazine and actuated by vertical sliding rods which in turn receive I 5 motion at their lower ends from power-dri ven keyboard devices. Itis the common practice to remove a magazine from the machine and substitute another having matrices for a different face ofV type. Preparatory' to this rezo moval of the magazine it is customary to slide back the guidein which the upper ends of the escapement-actuating rods are mounted in order to unhook their upper ends from the escapements. When this occurs, there is a z5 tendency of the rods to slide down in such position that their upper ends cannot be conveniently engaged with the escapements of the second magazine when it is applied. In the ordinary machine a locking-bar is provided for insertion transversely through the keyboard to lock the esoapement-rods in their elevated position; but it frequently happens that there is failure of the operator to place this bar in position, and the result is that the 3 5 rods` falling out of place lead to much trouble and annoyance.

The objects of my invention are, iirst, to

prevent the key-rods from falling or to limit their falling motion when they are disengaged 4o from the escapements, and, secondly, to provide for instantly raising them in series, so

that they may be conveniently engaged with the escapements.

Figure l presentsa vertical section through the mouth of the magazine, the keyboard con nections, and attendant parts, with my improvement applied thereto. Fig. 2-is an elevation from the rear looking in the direction of the arrow No. 2 in Fig. l. Fig. 3 is a top 5o plan view of the parts shown in the preceding figure. Fig. et is a section similar to Fig.

y with the escapements.

1 through the mouth of the magazincpand parts immediately adjacent thereto, the rods being shown in their elevated position.

Referring to the drawings, A represents the inclined magazine, in which the matrices B are carried, and C is one of the pivoted oscillatingescapements for releasing the matricesone at a time from one ot' the magazine-channels. Disan actuating-rod, urged downward 6o by spring N, having its upper end made in a hooked form to engage the escapement C. It is mounted in a guide E, arranged to slide forward and backward on the main frame P under the influence of crank-arms c in order to disengage the rods from and reen gage them At the lower end each rod D stands'directly over a pivoted vertically-swinging yoke F, slotted to receive a cam G, pivoted therein and standing nor- 7o mally in engagement with a stop-pin H,Which prevents its rotation. The yoke is held normally in anelevated position to keep the cam in engagement with its stop by a pivoted dog I, actuated bya vertical slide J, engaging one end of a finger-key lever K. Under the cam there is a constantly-rotating roll L, normally out of Contact with the cam. When a fingerkey is actuated, the dog I permits the yoke F to fall until the cam Gdsengages from stop 8a H and rests upon4 roll L, whereupon the frictional engagement of the roller causes the cam to revolve and the cam by reason of its eccentricity lifts the rod D until the latter yactuates the escapement and releases the matriX. As the finger-key is' released immediately after its depression, the dog I assumes the proper position to arrest the yoke in its original position after the escapement is actuated. f

The foregoing parts are all of ordinary construction and operate in the ordinary manner, as fully explained in Letters Patent issued to P. T. Dodge, No. 530,931, dated December 18, 1894. It will be understood, ot' course, that 95 there is an escapement, with its rod and iinger-key connections complete, for each channel of the magazine.

If the escapement-rods are pulled back out of engagement with the escapements C, they will in the ordinary machine immediately drop down so far that the upper ends cannot be IOO rengaged with the escapernents by the forward movement of guide E. In order to prevent this action, I form in the inner edge of the rod D a notchd, and across the machine from side to side I extend a bar M, seated in the notches of all the rods and serving to limit their downward motion. This bar M may be attached to any suitable support, but is preferably connected to the guide E by screws m in such manner that the bar M is allowed a limited vertical motion. This bar will without the aid of other parts overcome most of the difficulties which have been heretofore encountered. Inasmuch, however, -as the hooked ends of the rods D are most conveniently engaged with the escapements by rst raising them to an extreme height and then permitting them to fall as they are carried forward into engagement, I recommend the employment of means for lifting the bar M, so that it may raise the key-rods D above their normal position. A simple device for this purpose is a hand-lever O, having its forward end widened horizontally in the form of a plate to engage under the bar M and with fn-lcrum studs or bearings o, formed in the under side, so as to rest upon the frame-bar P. Then the rear end of this lever O is depressed, the forward end lifts the bar M, and thereby raises the hooked ends of the rods D, so `thatif the magazine is in position all of the rods may be easily engaged with the escapements by simply moving the guide E forward. The only requirement in this, regard is that the bar M shall be combined with ward and backward, and a bar M engaging the cross-bars substantially as described, to prevent them from falling when disengaged from the escapements.

3. The matrix-delivering escapements C in combination with their actuating-rods D, a movable guide E to effect the engagement and disengagement of said rods, a bar M to limit the descent of the rods, and means suhstantially as shown for lifting the bar'M, whereby the engagement of the rods with the escapements is facilitated.

In testimony whereof I hereunto set my hand, this 22d day of March, 1900,'in the presence of two attesling witnesses.
